How to choose the best no deposit bonus for you in May 2025

With a wide range of no deposit offers listed on this page, you may find it difficult to choose the best option for you. To help you make an informed decision, we’ve gathered the key information about all available bonuses and the casinos offering them. Use this data to compare the listed free casino bonus offers and pick your favorite.

Here are the four main factors to consider:

1. Casino offering the bonus – At Casino Guru, we aim to highlight the best online casinos with fair approach to gambling. These are the ones that have a high Safety Index based on our casino review methodology and reviews conducted by an expert team of 15+ reviewers. Always prioritize offers from gambling sites with a higher Safety Index.
2. Size of the bonus – You most likely want to get as many free spins or as much free bonus funds as possible. That said, we recommend you don’t choose solely based on the size, as unfair rules or unfavorable conditions can make it difficult to withdraw winnings, making the size of the bonus quite irrelevant.
3. Bonus rules and T&Cs – Based on our experience, these can make or break any casino bonus. We recommend looking at the wagering requirements, the maximum cashout, and other applicable rules that influence what you can and cannot do with your bonus funds. If you break the rules, you will not be allowed to withdraw your winnings.
4. Your preferences – Of course, you should also consider your own preferences, such as the games you like to play, the design of the casino offering the bonus, accepted payment methods, and so on. Gambling should first-and-foremost be enjoyable, and these subjective factors are important, too.

Fine-tune your search for the right offer

There are also other sorting options that let you rearrange the list of no deposit bonuses to your liking. If you wish to see the newest bonuses at the top of the list, select the 'Recently added' sort. Click on 'From just opened casinos' if you are interested in bonus offers from new casinos. There is also an option to reorder the list to display no deposit bonuses with the biggest value first.

If you are looking for something specific, feel free to use our filters. For example, you can find no deposit bonuses with your preferred bonus amount or number of free spins thanks to the 'Bonus Value' filter. You can also use the 'Maximum Cashout' filter to only see bonuses without cashout limits or set maximum WR of the bonus using the 'Wagering Requirements' filter.

As we have mentioned, no deposit bonuses are usually intended to attract new players to sign up at an online casino and try its services. However, some casinos also offer no deposit bonuses to existing players as part of some special promotion or as a loyalty reward.

If you have any specific requirements for the casino offering the bonus, our filters also have you covered. Simply check the 'Filter by casinos' section and apply your preferred filters to find only no deposit bonuses from casinos that best match your needs.

No deposit bonus activation – promo codes and instructions

In order to get a no deposit bonus from a casino, you need to follow the casino's instructions. In many cases, the bonus will be added to your account automatically once you register. However, you will often need to use a promo code or go to a separate page dedicated to bonuses and promotions to activate your offer.

The instructions for each offer in our database are clearly displayed next to the no deposit bonus above in the 'How to get bonus?' box. Below, we will cover the main bonus activation types in general.

1. Automatic activation

As already mentioned, casinos often add a no deposit bonus to your account automatically. In these cases, we do not display any instructions above, as they are not necessary. You simply need to go through the registration and the free bonus will be waiting for you in your account.

2. No deposit bonus code

If you can see a bonus code listed next to an offer above, you will need to use the code to get your free bonus. Specifics on how the code should be used differ from casino to casino, but usually fall into one of these categories:

• Enter code during registration – Some casinos have a bonus code field right in the registration form. In this case, you need to enter the bonus code during the registration process.
• Enter code in your account – Other times, you need to find a place to insert the bonus code after the registration, usually in the casino account management interface or at a page dedicated to bonuses and promotions.
• Send code to customer support – Some casinos do not have any specific field to enter the bonus code. In these cases, you can contact the casino's customer support and send the bonus code to them.

3. Activate bonus during or after registration

Online casinos often offer multiple bonus options to new players, allowing them to choose the bonus they would like to claim from the offered options.

This is often done right during the registration process, where you can choose the no deposit bonus you would like to claim. Simply select your preferred option and proceed with the registration. The no deposit bonus should be waiting for you in your account once your registration is completed.

Alternatively, it can be done after the registration itself, once you are logged in. Each casino does it differently, but you will usually find the no deposit bonuses you can activate in your account settings, in the cashier section, or at a separate page focusing on the casino's bonuses and promotion.

4. Other ways of bonus activation

We have more than 6,000 online casino sites in our database, so it comes as no surprise that some of them may require you to complete a different procedure to activate the bonus. This could include unique bonus activation steps like contacting the live chat, sending an e-mail, or similar.

To make sure you complete all the necessary steps, it is important to always check the specific instructions for each no deposit casino bonus before claiming it.

What are casino no deposit bonuses?

Casino bonuses are often divided into two groups – no deposit bonuses and deposit bonuses. As their name suggests, no deposit bonuses do not require players to make a real money deposit in order to be claimed.

This makes no deposit bonuses essentially free, as players can use them to play casino games without spending any of their own money. Of course, this makes them extremely popular amongst players, who welcome the opportunity to play casino games for free and have a chance to win real money in the process.

Most of the offers you will find on this page are no deposit bonuses for new players. Casinos use these free casino bonus offers and codes to stand out from the competition and motivate players to sign up and start playing.

Of course, online casino sites also offer no deposit bonuses to existing players. This is commonly done to reward players as part of the casino's loyalty scheme or during special promotional campaigns.

If you decide to claim a no deposit bonus, keep in mind that there are many rules in place when playing with one. These dictate what you can and cannot do. If you do not follow the rules, the casino may confiscate your bonus and any accumulated winnings. You can find more information about these rules below.

Types of no deposit casino bonuses and bonus codes

There are many ways to classify no deposit bonuses offered by casinos. In terms of what you get when you claim or activate a bonus, no deposit offers can take one of these forms:

• Free cash no deposit – With free cash bonuses, you get a certain amount of bonus funds added to your account. You can usually play a wide range of available slots and casino games with your free cash, although there may be some limitations, which we will cover below.
• Free spins no deposit – When you get a free spin bonus, the casino adds a number of prepaid spins to your account. These are usually usable solely on online slots, and often limited to a single specific game or a small number of games. This means that you have to stick to one of the selected no deposit bonus slots in most cases, which may be less enjoyable than playing your preferred titles.
• Free bets – Many online casinos also offer sports betting services. As a result, you may find some casinos offering free bets on sports matches. That said, you will not find these on Casino Guru, as we focus on casino games and bonuses that can be used on casino games.

On top of that, here are some other types of no deposit bonuses we find worth mentioning:

• No deposit bonuses for new players – Any no deposit bonus given to newly registered players falls into this category, also known as registration no deposit bonuses. These bonuses are used by casinos to give players an incentive to create a new account and start playing.
• No deposit bonuses for existing players – Online casinos also give a free bonus no deposit to to their existing players, most commonly to reward them for their loyalty or give them an incentive to start playing again.
• No deposit bonus codes – Casino bonuses are often activated using a specific bonus code that must be entered during registration or otherwise used to get the bonus. In our database of offers above, you will see the specific promo code listed next to any bonus that requires it.
• Zero wagering no deposit bonuses – Generally, players need to play with their bonus funds and meet its wagering requirements before being able to withdraw their winnings (more on this below). Zero wagering bonuses come without this requirement and can be cashed out instantly, although they are not very common.
• Exclusive no deposit bonuses – When a bonus is exclusive, it means it is only offered to some players or through certain channels. For example, you can find exclusive no deposit bonuses on Casino Guru, which means they are only available to our visitors.
• Time-limited no deposit bonuses – Some free bonuses are only available for some time, as a special offer on a given day, a weekend, or another period of time. You can find these in the 'Limited time' tab above.

Terms and conditions of real money no deposit bonuses

Most bonuses offered by online casinos – including those that do not require a real money deposit – come with certain rules that must be followed during bonus play, as well as limitations that apply to it. These are specified by the casino in the Terms and Conditions (T&Cs) that apply to bonuses.

So that you know what to expect, here are some of the most common T&Cs of no deposit casino bonuses:

• Wagering requirements (WR) – As mentioned above, in most cases you cannot withdraw your bonus funds before wagering a certain amount of money. This is known as wagering (or playthrough) requirements, which are usually specified as a multiple of the bonus you get. Once you wager the required amount, you can withdraw your bonus and any winnings you won from it.
• Maximum win – Also known as maximum cashout, this condition specifies how much you can win and withdraw from your bonus. Casinos use this limitation often, especially for no deposit bonus codes, to make sure that players do not win too much without risking any of their own money.
• Maximum bet – When playing with most casino bonuses, you will also have to adhere to the max bet rule. The maximum bet of most bonuses lies somewhere around the €/£/$5 mark. If you place a bet higher than that while playing with a bonus, the casino may refuse to pay out your winnings.
• Game restrictions – It may also be prohibited to play certain games with the no deposit bonus. This means that you may not be able to play your favorite casino games using bonus funds. Ideally, the casino will not let you play these games at all, but it is also possible that they may use playing restricted games as a reason to void your winnings from the bonus.
• Wagering contribution – Some games may be configured in such a way that they do not contribute 100% of the wagered funds towards the wagering requirements, meaning that only a certain percentage of the bets may count towards the WR, or none at all.
• Country restrictions – Casinos often offer bonuses only to players from selected countries. Alternatively, players from different countries may have access to a different set of promotional offers.
• Time limits – Many bonuses come with an expiration period, which means you must play with the bonus and meet the wagering requirements within a certain timeframe.
• One bonus per player – Most casino bonuses, and virtually all no deposit offers for new players, can be used only once. You can usually only create one account in a specific casino, and registration bonuses can only be used once. Casinos are very careful about this and will not pay out any player who breaches this rule. So, instead of trying to use a bonus multiple times, we suggest looking for other bonuses on this page or other websites, such as lcb.org.
• IP or household restrictions – Similarly, casinos often limit their offers to one bonus per household or IP address. If two people from the same household play at the same casino, only one of them may be eligible to claim a no deposit bonus. To add to that, many casinos do not allow multiple people from the same household to play altogether, so make sure to read the casino's T&Cs if you plan to do that.

These are just some of the most common T&Cs of no deposit casino bonus offers. The full list of rules and limitations is listed next to each offer, while the full version of the T&Cs of a specific bonus can be found directly on the casino's website.

Also, it is worth noting that some offers consist of multiple part, such as some bonus funds and a number of free spins. In this case, the individual parts may come with a different set of rules and limitations.

Before you claim a no deposit bonus, we recommend that you always check its terms and conditions. This way, you are more likely to avoid any unwanted surprises like high wagering requirements, low bet limits, or game restrictions. You surely want to claim bonuses only from safe online casinos that treat players fairly, so don't forget to also check the Safety Index of the casino site that is offering the no deposit bonus.

Pros and cons of no deposit casino bonuses

Of course, no deposit bonuses come with certain advantages and disadvantages that players who consider claiming them should be aware of.

When you play with a no deposit bonus, you don't need to deposit your own money into your casino account to start playing and, therefore, you don't have to worry about losing your money. Moreover, you are given the chance to win some real money if you get really lucky.

The fact that you are not risking your money when you claim a no deposit bonus at a new casino allows you to try different casino sites and find out which one you like the most. On top of that, the process of claiming a no deposit bonus is generally very easy and straightforward.

On the other hand, there are also several disadvantages of claiming a no deposit bonus, such as the wagering requirements that you need to meet in order to claim any potential winnings from the bonus. What's more, the amount of bonus funds you receive is typically small, so even if you get lucky and win, the win amount is likely to be quite small, too.

No deposit bonuses also tend to come with short expiration periods, so sometimes you may not manage to meet the wagering requirements in time before the bonus expires. Additionally, some games may be restricted for play with bonus funds, so you may not get to play your favorite titles.

To provide you with a clear overview, we've summarized some of the pros and cons of playing with no deposit casino bonuses in the table below.
